Abstract
Ispitano je vezanje iona olova iz vodenih otopina na prirodnom zeolitu u prisutsvu organske tvari. Simulacija organske tvari izvedena je dodatkom vodene otopine preparata Fertireg ® različitih početnih koncentracija. Fertireg ® je trgovački naziv za organsko gnojivo koje ima visoku koncentraciju fulvinskih i drugih organskih kiselina koje se nalaze u tlu u prirodi. Utvrđeno je da ne dolazi do kompleksiranja olova u otopini Fertireg ® za obje početne koncentracije. Također je uočeno malo odstupanje u točnosti određivanja koncentracije olova zbog nemogućnosti određivanja točke ekvivalencije. Vezanje iona olova na zeolitu u suspenziji bez i s dodatkom otopine Fertireg ® ne pokazuje značajna odstupanja u količini vezanog olova po gramu zeolita. Može se zaključiti da organsko gnojivo Fertireg ® u navedenim eksperimentalnim uvjetima ne bi trebalo imati utjecaj na remedijaciju tla onečišćenog ionima olova korištenjem prirodnog zeolita.
Abstract (english)
The removal of lead ions from aqueous solutions on natural zeolite in the presence of organic matter has been examined. The simulation of organic matter has carried out by preparation of aqueous solution of the Fertireg ® of different initial concentrations. The Fertireg® is a trade name for organic fertilizer which contains high content of fulvic and other organic acids, which are found in the soil in nature. It was found that no precipitation of lead occurs in the Fertireg ® solution for both initial concentrations. A small deviation in the accuracy of determining the lead concentration has been observed due to the impossibility of determining the equivalence point. The binding of lead ions on zeolite in suspension without and with the addition of Fertireg ® solution does not show significant deviations in the amount of bound lead per gram of zeolite. It can be concluded that Fertireg ® organic fertilizer in the mentioned experimental conditions should not have an impact on the remediation of soil contaminated with lead ions using natural zeolite.
